Revealing mistake: When the spear handle is protruding from Hector's shoulder, the area of the armor around the circular wound is clearly visible and it is in perfect condition. There is no tear in the armor whatsoever, around the wood, which would have been necessary to allow the wide spear tip to penetrate the armor and actually enter Hector's body as it did.

Revealing mistake: Just before the Roman soldiers pressed Simon of Cyrene to help Jesus carry the cross, Jesus has fallen and we see that the bruised and swollen-shut eye is now his left. The shot changes and when it comes back to Jesus his right eye is swollen shut again. The film must have been flipped.
